Abstract

For safety and security for both the workers around the railway tracks and railroad operators, early identification and warning of an approaching train is most important to give workers time to get off the track and remove tools from the track. Experiments have been conducted at a seamless steel railway to spot vibration symptoms of approaching freight trains and passenger trains. Various vibration sensors and frequency ranges are used. As a result, an approaching train can be reliably detected by vibration at a specific frequency with a lead time of about 30 seconds.
